I did a search but nothing answered my question really and most were for Tc's.

I just ordered the Unorthodox Racing Ultra S Lightened Aluminum Underdrive Crank Pulley for my xA but I keep hearing negative things from the shops like nothing runs the same after. They say they do not recommend it if I am not gonna race my car??

Should I return the damn thing then?

 

you'll be fine

 

Will I notice anything good? or anything bad??

 

Also I think you have a manual trans. I am Automatic.

 

what negative things are they saying? the only bad thing that i know off, is the roughness of the engine after you install aftermarket pulley. So if you dont mine a louder, rougher engine, (during drive and idle) then go with it.

 

it just slows down the accessory pullies so that the engine doesn't have to work as hard to spin everything it allows more of the horsepower generated by the engine to be sent to the wheels.

 

I'd suggest going with the Perrin lightwieght pulley because of the long term wear an underdrive pulley can do.

 

Thanks both of you. I will try and return the Unorthodox and get the Perrin. I did not know there was any difference before I ordered it and it's already in the mail

 

Bump:

I put it up for sale or trade. Damn Ptuning wants to take 20% on a return even if I don't open it. The auto industry in the US is so FOS! No wonder Ford is a dying breed of car company. "RANT"

 

How would you guys rate the Agency Power Crank Pulley vs. the Perrin Crank Pulley?? Gonna get one of them this week as I have RMA'd the Unorthodox.

 

I ended up getting the Agency Power Crank Pulley cause they came in red still need to get it installed.

 

i havent installed a pulley on my box yet, but i did install one on one of my other cars, i didnt really notice a difference in the way the engine ran, noise wise, but i did have an exhaust and cai, but the car was definitly perkier.

 

Perkier is not such a bad word to hear. I hope when I install it I will be happy. I also have a CF hood going on soon!

 

Got the Agency Pulley and I am now looking to find the nut which secures the crank pulley since I have been HIGHLY recommended to get a new one. It's not made to be re-used once it's taken off.

Anyone know the part number??

 

what what? who's telling you such things? as far as I know everyone who's installed a pulley has re-used the same bolt and had no issues. Have you seen the install threads? They have pictures and everything of the BOLT, not a nut.

 

En quote "one common mistake a lot of people do which i forgot to mention is do NOT reuse the nut which secures the crank pulley. It is designed to only be used once, and I'm sure you've read the horror stories of peoples "crank pulleys" falling off. The bolt is like 5 dollars from the dealer and well worth the money spent."

Oh, and I had to drive to the dealership to order and pay for it. "New procedure" they say. I gotta go there again to pick it up Thursday/Friday.
